I keep reading posts where you guys are putting 10-15psi on these stock gsr's without blowing them up. Why would all these tuner recommend not boosting over 7psi on stock internal when a lot of you guys are going well over that and still running strong?

I know they want to play it safe but is there any difference between 7 or 9psi spring with a little creep up to 10 or 11 psi

reliability i would guess

same ol Steve

turbo size is more important than psi, 15 psi from a gt42 is a lot more airflow than from a gt15. Using psi is kind of a false indicator unless the turbos are identical.

its a t3/t4 setup that comes with a peakboost kit

57 trim? or what? Just run ten, you'll be happy. You'll put down about 300ish whp.

good question its what comes with the FTW kit ill have to call ken and ask.

look! my car tuned @ .6bar spring (10.9psi boost spike), 395hp stock gsr block and modified head.......
but on the streets i can barely see boost probably 5psi max and that is, unless i want to hit he gas and leave tire mark's on the road....not safe
feels like driving a ferrari without insurance IMO.
most of the time im driving @ -10 vac and this is just a t3/t67 stage 5

no worries!

thanks, i decided to go with the 9psi spring

and when u wanna turn the boost up (which you will) just get a boost controller!

your turbo kit should come with the 50trim t3/to4e unless you tell them you want a 57 or 60trim. cause i got the same kit and asked which one comes with it and they said the standard size is 50 trim so i got the 57trim.

Grab a MAP Sensor at least.

^^good choice because eventually when you feel like boosting over 11psi you will already be good to go and wont have to buy one down then road and then get a new re-tune.

good point thanks
